A Reservoir Under Our Feet
Water providers in the Sacramento region are developing the Sacramento Regional Water Bank (Water Bank). The Water Bank is an innovative groundwater storage program that will improve regional water supply reliability in the near-term and into the future. The Sacramento region’s unique setting—at the confluence of the Sacramento and American rivers near Folsom Reservoir and overlying the North American and South American groundwater subbasins—is ideal for the Water Bank’s development.

The Water Bank will allow the region to sustainably increase use of groundwater as a local water source during dry periods, allowing reduced surface water diversions to help meet local environmental needs. In addition, the region’s location north of the Sacramento-San Joaquin Delta provides potential opportunities to collaborate and develop solutions to benefit the environment and communities downstream after local needs are met.

An Untapped Regional Asset
The Water Bank represents many years of regional planning by diverse local stakeholders. It continues the region’s commitment to the principles of the Sacramento Water Forum, established more than two decades ago, to promote and implement sustainable water management practices such as conjunctive use that balance water supply needs and the environmental health of the lower American River. These practices include the expansion of conjunctive use. Building on the success of recent conjunctive use projects, the region recently completed a Regional Water Reliability Plan that identified substantial opportunities for expanding conjunctive use.
